Find the complement of the following angle:$47^\circ$

SOLUTION
Two angles are said to be complementary if the sum of their measures is $90^\circ.$
The given angle is $47^\circ$
Let the measure of its complement be $x^\circ$.
Then,
$\implies x + 47 = 90$
$\implies x = 90 - 47$
$\implies x = 43^\circ$
Hence, the complement of the given angle measures $43^\circ.$
